Cerebroprotein hydrolysate, preparation method thereof and composition containing cerebroprotein hydrolysate

Abstract

The invention relates to the field of food processing, and particularly discloses a cerebroprotein hydrolysate, a preparation method thereof and a composition containing the cerebroprotein hydrolysate. The preparation method of the cerebroprotein hydrolysate comprises the following steps: tissue homogenization, enzyme activity inactivation, enzymolysis, high-temperature sterilization, centrifugal concentration, degreasing and post-treatment. Wherein the homogenate is subjected to high-temperature passivation treatment, so that the enzymolysis efficiency can be improved, after the enzymatic hydrolysate is subjected to centrifugal concentration treatment, the use amount of acetone during degreasing can be reduced, finally, residual acetone can be removed through drying treatment, and the preparation method has the advantages of being simple in process, high in degreasing efficiency and high in hydrolysate extraction efficiency. The cerebroprotein hydrolysate can be directly eaten and can also be eaten in cooperation with other raw materials, and the cerebroprotein hydrolysate prepared through the method is fine and smooth in texture, small in fishy smell, light in color, high in amino acid content, polypeptide content, total ganglioside content and total sialic acid content and low in fat and cholesterol content.

Description

Technical field [0001] The present application relates to the field of food processing, and more specifically, it relates to cerebral protein hydrolyzatics and preparation methods thereof and compositions comprising brain hydrolyzate. Background technique [0002] Ethylene protein hydrolyza refers to a mixture of hydrolyzed, protein, amino acid, and the like from animal brain tissue, which can act on human neurotic tissue, can improve nerve cell metabolism, promote protein synthesis of neural cells, and protect nerves. Cells are from ischemia and neurotoxin damage, with the role of improving symptoms such as insomnia, headache, memory loss, dizziness and irritability. [0003] In the relevant technique, the preparation method of brain hydrolyza usually includes the following steps: animal brain tissue → pre-treatment → homogenate → enzymatic hydrolysis → centrifugal → ultrafiltration → column chromatography → sterilization. Due to high fat and cholesterol in the animal brain (suc...

AI Technical Summary

Problems solved by technology

The common degreasing method is to use acetone or acetone composite solvent for degreasing, which has the advantages of simple operation and high degreasing efficiency, but there is also the problem of large solvent usage

Other methods of degreasing, such as carbon dioxide supercritical extraction and milk fat separator degreasing, although high in safety, require the use of special equipment, which not only increases the cost of equipment investment, but also has the defects of cumbersome operation and decreased yield of active peptides.
